Abstract: A drive-off prevention controller for a dynamic positioning system, the drive off prevention controller being configured to communicate with the dynamic positioning system, wherein the dynamic positioning system is configured to determine a position of a vessel relative to a target position and to control a propulsion system of the vessel based on the determined position of the vessel relative to the target position; and the drive-off prevention controller is configured to, based on one or more indicative conditions, selectively adjust the control of the propulsion system determined by the dynamic positioning system or that would otherwise have been determined by the dynamic positioning system; and at least one of the indicative conditions comprises the demand, or rate of increase in demand, of the propulsion system being greater than a first conditional threshold whilst weather or environmental data received by the drive-off prevention controller indicates that there has been no corresponding change in weather or environmental conditions.

Abstract: A flywheel system including a rotor forming an aperture extending through a rotation axis of the rotor and a fixture including a shaft assembly for passing through the aperture of the rotor, wherein the rotor rotates about the shaft assembly. The shaft assembly includes a bottom support, a top support, a central rod connecting the bottom support to the top support, a plurality of stacked modules, each module forming an aperture for receiving the central rod, a top pre-tensioning nut affixed to a top end of the central rod, and a bottom pretensioning nut affixed to a bottom end of the central rod. The top pre-tensioning nut and the bottom pre-tensioning nut clamp the plurality of stacked modules between the bottom support and the top support.

Abstract: An offshore drilling vessel includes a hull and at least one opening in the hull arranged to receive an end of at least one submersible cable. The offshore drilling vessel also comprises a cable capture mechanism configured to lift the end of the at least one submersible cable through the at least one opening from a submersed position to a raised position. A cable connector is configured to couple to the end of the at least one submersible cable when the end of the at least one submersible cable is in the raised position such that the offshore drilling vessel comprises an external data and/or power connection via the submersible cable.

Abstract: A method for operating a microgrid electric power generation system includes delivering energy to an electric power bus at least partially from one or more kinetic generators electrically coupled to the electric power bus, controlling the one or more kinetic generators in response to a change in a load such that a magnitude of a voltage on the electric power bus remains within a predetermined voltage range, and controlling one or more combustion generators electrically coupled to the electric power bus based at least in part on an operating state of the one or more kinetic generators. The one or more kinetic generators are capable of (a) delivering energy stored therein to the electric power bus, and (b) storing energy in kinetic form.
